I was a bit dubious about this kit, I have had a brazillian blowdry in a salon, but cant afford to have this done all the time so I bought this kit to try and do it myself.
The advert says it is formaldehyde free, but there is a similar chemical in this product, although well down the list of ingredients, so I used very sparingly and have more than 3/4 left for future use.
I have very fine, greasy hair, with annoying kinks caused by the scottish wind and rain. I would spend 15 minutes every day making my hair presentable, only to have all my hard work destroyed before I got to the end of the road! This kit has cut my styling time to less than 5 mins from wet, and my hair is resilliant to the weather - even if it gets wet, once dry my hair is presentable. Also in the morning when I get up, my hair looks ruffled instead of a complete disaster! Definately a success. Just have to see how it lasts but like I said, I have plenty left for re-treatment.
After this treatment, it is necessary to use sodium free products on your hair, some of which are very expensive but SAMY Jooouge range from Superdrug is not only very affordable and sodium free, but adds a bit of bounce back instead of your hair being so flat it sticks to your head!
